Shell small (3.3 mm), thin, white, arched, high (SH/SL = 0.45). Apex well posterior of center (P/ SL = 0.89). Protoconch well below apex, 172 µm in length, with posterior margin embedded in posterior slope of shell. Protoconch smooth, with densely but irregularly scattered fine crystals. Teleoconch sculpture of raised concentric bands that, with increasing shell size, become irregular, then interrupted into beads or pustules that align to form regularly curved rows. Radial sculpture of very fine, irregular, threads and beads that abut but do not cross concentric bands. Anterior slope strongly convex, posterior slope weakly concave. Aperture roughly planar, broadly elliptical. Shell edge thin, sharp. Periostracum thin.

The posterior position of the apex, the distinctive arched shell, and the distinctive sculpture of the protoconch and teleoconch readily identify this species.

Previously known only from the type locality, off Grand Bahama Island, Bahama Islands at a depth of 412 m (McLean & Harasewych 1995). The present record extends the range to off the Caribbean coast of Colombia, and the depth range to 89 m.
